6.6 SMI# interrupt mode

The HM_SMI#/OVT# pin is a multi-function pin. The function is selected at Configuration Register

CR[29h] bit 6.

6.6.1 Voltage SMI# mode

SMI# interrupt for voltage is Two-Times Interrupt Mode. Voltage exceeding high limit or going below

low limit will causes an interrupt if the previous interrupt has been reset by reading all the interrupt

Status Register. (Figure 6.12 )

6.6.2 Fan SMI# mode

SMI# interrupt for fan is Two-Times Interrupt Mode. Fan count exceeding the limit, or exceeding and

then going below the limit, will causes an interrupt if the previous interrupt has been reset by reading

all the interrupt Status Register. (Figure 6.13 )
